[vsnet-alert 14816] Re: PNV J09410000-5759540

Hi,

I am experiencing computer problem with my main PC, so will take some time until I get back with more measurements.

Weather is also a bit changing in Chile. Got data last nioght but am not sure if usable.

Need to wait to get again access to my PC.

Regards,

JOsch

Clear skies here last night and tonight, and I imaged the PNV at 200mm
(DSLR unfiltered).  Bright moonlight and low altitude.  Seems about the
same brightness to me both nights, around 10.0 unfiltered.  I'm a
bit hesitant about making estimates though because it's so red.

Last night's (09:47, 29 July 2012 UT):

Tonight's (10:42, 30 July 2012 UT):

Looking forward to some more photometry & a spectrum when Josch, Terry and
others get clear sky.
